On 26 November 2011, gandul.info posted the above photo. Apparently the Banca Naţională a României created 500 banknote-like numismatic products to commemorate the bank’s 130th anniversary. If you examine the images below, you’ll see these are not banknotes. They aren’t denominated in Romanian leu, and the “serial numbers” on back simply indicate the 130 A (ani = year) span between 1881 and 2011.
